SHIP-PROTECTOR.

Application filed. July 10, 1918.

To all whom t may concern:

Be it known that I, PETER SANGOFF, a citizen of Russia, residing atQuincy, county of Norfolk, and State of Massachusetts, have inventedcertain new and useful Improvements in Ship-Protectors, lof which thefollowing is a specification.

This invention relates to improvements in devices for protectingsea-going ships from submarine attacks and has' as one of its principalobjects the provision of means whereby a ship may be protected againsttorpedoes, mines and the like.

Another object is to provide means where* by the ship is also protectedagainst bombs dropping from above.

Further objects are to provide the protecting devices with resilientmeans of support so that the shock or impact of blows, given eitherlaterally or from above, are absorbed and not transmitted to the ship.

These and other like objects are attained by the novel construction andcombination of parts hereinafter described and shown in the accompanyingdrawings, forming a material part of this specification, and in whichFigure 1 is a side elevational view showing a conventional type of shipand the arrangement of protective devices at the sides and over the topthereof.

Fig. 2 is a top plan view of the same.

F ig. 3 is a front elevational view thereof.

Fig. 4 is an enlarged fragmentary transverse sectional view takenthrough the hull showing one of the side fending elements and itssupports.

Fig. 5 is a similar view of the same, but showing a modification inwhich the fending elements may be stressed with respect to theirsupports.

Fig. 6 is a fragmentary front view, partially in section of the bombprotector as arranged over the ship.

Fig. 7 is a fragmentary plan view of the same.

Fig. 8 is a fragmentary side elevational view, showing a modified formof bomb protector, and

Fig. 9 is a fragmentary top plan view of the same.

Referring to the drawings, Figs. 1, 2 and 3 show a conventional type ofship 10, provided with all the various paraphernalia Specification ofLetters Patent.

and mechanisms used in navigating the same.

Firmly secured to the hull of the ship 10 are brackets 14, the samebeing arranged at spaced intervals completely around the hull and inrows one above the other.

Extending horizontally outward from the brackets are rods 15, at theouter ends of which are secured armor plates 16, the same being held inposition on the rod by collars 17, pinned directly to the rods. Thesearmor plates are pressed outwardly against the collars by the action ofcoiled compression springs 18, the same being tensioned by the collars19 also secured rigidly to the rods 15, this construction being clearlyevident in Fig. 4 of the drawings.

In the modification shown in Fig. 5, the outer ends of the rods 15 arethreaded, as at 20, and encircled by sleeves 22, thereby permitting thesleeves, which are threaded to the rods, to be moved to or from thehull, the sleeves having exterior flanged ends 23 upon which the armorplates 16 are engaged, the armor plates being pressed outward, due tothe effect of the coiled compression springs 24, which in themselves canbe adjusted, by the nuts 25, threaded on the sleeves 22, this latterarrangment affording means for extending or retracting the armor plates16 with reference to the hull 10, the armor plates sliding along thesleeves 21 under the impact of a blow, as from a projectile, thusaffording an efficient guard against under-sea projectiles.

In order to provide a defense against aerial missiles, such as bombs orthe like, which may be dropped from a height by an aeroplane or otheraerial carrier, there is arranged contiguous to the gunwale of the ship,a plurality of upright posts 30 along the sides and ends of the ship,the same eX- tending to a considerable height thereabove so as to clearthe entire structure of the ship, including the look-out box, the postsbeing arranged in opposed pairs, and secured to the upper part of theposts are lugs 31 containing eyes in which are secured the outer ends ofcoiled tension springs 32, the inner ends of the springs being engagedwith similar eyes or equivalent openings formed in the cover plates 33,one or more of which may be used in a superposed relation as shown inFigs. 1 and 3..

From the foregoing it will be obvious that7 due to the large area of theplates 33, their construction must be of adequate strength and also beextremely light.

F or this purpose the modification shown in Fig. 9 is consideredpreferable', the same consisting of bent hangers 35, rigidly secured inthe eyes 31, their loiver ends being coiled about rods 36, to which areengaged the edges of a resilient net 38, thereby dispensing with thenecessity of the springs 32, the net being of such magnitude as toreceive the blow of a bomb or like aerial object and prevent it fromdropping through to the deck of the ship, the net causing the bombeither to rebound or to rest quietly upon its surface without doingdamage.

It is to be understood that the various devices shown are to beconsidered only as illustrative and obviously any modification may bemade Without departing from the scope of the invention as indicated bythe appended claim.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is.

In an aerial bomb protector for ships, the combination With the hull ofa ship, of a plurality of vertical posts engaged with the edge of thegunWale of a ship extending above the highest portion of the shipssuperstructure, a plurality of superposed coverplates, and coiledtension springs for securing said cover-plates to said vertical posts,substantially as described and for the purpose set forth.

In testimony whereof I have affixed my signature this twenty ninth dayof June,

PETER SANGOFF.
